Supplier documentation profile
Arizen BioLabs
Arizen BioLabs publishes a no-login COA gallery and states that tested lots receive independent purity and identity analysis. Report-to-lot traceability, laboratory accreditation, and consistent contamination-testing coverage still require verification.

Procurement details
Business policies not yet documented
PDD has not yet preserved dated, directly reviewable records for this supplier's ship-from location, regions served, processing time, free-shipping threshold, payment methods, or refund and replacement policy. We do not infer those details from a storefront location or checkout availability.
This section will expand into field-level records as eligible supplier policies are documented.
Evidence ledger
What the reviewed records support
Evidence and COA records last reviewed September 7, 2026. Missing documentation remains visible and is not converted into a negative claim.
| Review field | State | Finding and limitation | Basis |
|---|---|---|---|
| Public COA access | Documented | A public, no-login gallery displays available certificate images for multiple catalog products. | COA gallery |
| Lot traceability | Unresolved | The extracted gallery index identifies products, but a consistent connection among report identifiers, current inventory, and physical-vial lot labels was not established in this pass. | COA gallery + sampled product page |
| Laboratory provenance | Supplier-reported | The supplier describes testing as independent and performed by accredited U.S. laboratories; the issuing laboratories and accreditation status still require separate verification. | Homepage + about + COA gallery |
| Chromatographic purity | Supplier-reported | The supplier states that HPLC is used for purity and advertises a 99%+ benchmark. Complete chromatograms, methods, and acceptance criteria have not yet been preserved across current lots. | Homepage + COA gallery + sampled product page |
| Molecular identity | Supplier-reported | Mass spectrometry is named as an identity method, but report-level spectra and acceptance criteria remain to be reviewed. | COA gallery + sampled product page |
| Measured quantity | Supplier-reported | The homepage describes content verification as part of its testing panel; consistent lot-matched quantitative results were not established from the records reviewed. | Homepage testing description |
| Sterility testing | Supplier-reported | The supplier describes sterility culture testing, but consistent lot-matched sterility reports were not preserved in this initial review. | Homepage testing description |
| Endotoxin testing | Supplier-reported | The supplier describes endotoxin testing, but consistent lot-matched endotoxin reports were not preserved in this initial review. | Homepage testing description |
| Research-use positioning | Documented | The homepage, COA gallery, and sampled product page restrict products to qualified laboratory, in-vitro, and preclinical research and exclude human and veterinary use. | Homepage + COA gallery + sampled product page |

Evidence definitions
Documented
Connected to a directly reviewable public record.
Supplier-reported
Stated by the supplier but not independently confirmed.
Unresolved
The records reviewed do not support a conclusion either way.
Contradicted
Available records or statements materially disagree.
Open verification work
- Preserve representative complete reports and connect each one to a current catalog item and vial lot identifier.
- Verify the issuing laboratories and any accreditation claims independently.
- Record the HPLC, mass-spectrometry, content, sterility, and endotoxin methods and acceptance criteria by lot.
- Confirm the affiliate program's written attribution and qualifying-order terms.
